As mentioned in the cast list, Jamie Hyneman (who brought his trademark beret) and Adam Savage - who got their start as special effects experts - made cameos as lab technicians. Specifically, they watch and take notes when Nick tests whether a stun gun can set a perp's shirt on fire after the perp has been maced. Subsequently, the two of them subsequently received many requests to put that premise to the test on MythBusters, and in a 2010 episode called Fireball Stun Gun, they did just that.

Basing their analysis on the fire triangle, the two of them found that the myth was plausible because some pepper sprays use oil-based propellant (which makes the mace flammable), stun guns can create a big spark especially if they get caught in the target's clothing, and acrylic fabric (which is used to make flannel shirts like the ones seen in Theory of Everything) is in itself flammable. It is worth noting, though, that while they were able to achieve ignition with a stun gun and one can of mace on an acrylic shirt, they found that they only got a similar fireball to the one seen in Theory of Everything after the shirt had been soaked with eight cans' worth of pepper spray.
